TECHNICAL FIELD OF THE INVENTION

This invention relates generally to mobile computing devices, and more particularly to a method of informing a user about received calls or messages through haptic signals.

BACKGROUND OF THE INVENTION

Cell phones, particularly smart phones, are becoming more ubiquitous and versatile. As demand grew, cell phones design also grew to support more functionality including telephone calls, emails, text messages, web browsing, Instant Messaging, social networking, and scheduling. When any of these functions receives a communication (for example, a call or an email), the cell phone notifies the user through a visual or audio signal. The user may then check the cell phone's display to view information about the received communication (for example, the source or urgency of the communication).

However, it may not always be convenient for the user to check his phone when the communication is received. For example, the user may be in a meeting, where it is hard to watch a display or to listen to a voice feature. Furthermore, the user may have to navigate through several windows and menus before ever seeing the information about the received communication.

SUMMARY OF THE INVENTION

According to one embodiment, a mobile communication device is provided that includes a receiver, a ringer, and a signal generator. The receiver may be configured to receive a swipe indicating a user query for the source of a received call or message. The ringer may be configured to produce an audible signal when the computing device receives a call or message. The mobile communication device may be operable to silence the ringer. The signal generator may be configured to generate a vibration with a first intensity corresponding to a first classification of the source of the call or message and with a second intensity corresponding to a second classification of the source of the received call or message.

According to another embodiment, a method for informing a user through haptic signals may begin by receiving, at a mobile computing device, a user query for information regarding a received call or message. The user query may include some physical act performed on the mobile computing device. The method further includes generating, by the mobile computing device, a haptic signal to indicate a response to the user query for the information regarding the call or message.

According to yet another embodiment, a computing device is provided that includes a receiver and a signal generator. The receiver may be configured to receive a user query for information regarding a received call or message. The user query may include a physical act performed on the computing device. The signal generator may be configured to generate a haptic signal indicating a response to the user query for the information regarding the call or message.

Technical advantages of certain embodiments of the present disclosure include providing a user a way to check for information about received calls or messages without disturbing others. Specifically, only the user may perceive the haptic signal generated in response to his query for information. Other technical advantages will be readily apparent to one skilled in the art from the following figures, descriptions, and claims. Moreover, while specific advantages have been enumerated above, various embodiments may include all, some or none of the enumerated advantages.
